Feature: Semiconductors


semiconductor manufacturing, particularly for industrial automation and control systems, powering devices like sensors, actuators, and robotic systems over the same Ethernet cables used for communication. As another example, Arista’s Powered


by PoE (Power over Ethernet) panel PC streamlines the deployment of KPI displays across the plant floor by simplifying installation, reducing cabling complexity, and enhancing flexibility in device placement. With power and data transmitted through


a single Ethernet cable, installation is more efficient, reducing time and labour costs. Manufacturers can deploy a PoE-enabled device like a panel PC within 330 feet of the network switch using a single Ethernet cable. Tis eliminates the cost and inconvenience of having an electrical contractor run wiring. Tese devices are particularly suitable for applications where it may be costly or difficult to run extra wiring. Centralised power management also


enhances operational efficiency, as power can be monitored and controlled remotely through the network switch. Some PoE switches even allow individual ports to be turned on or off as needed, improving control over energy consumption. Te cost- effectiveness of PoE technology is another advantage, as using a single cable for both power and data reduces infrastructure expenses. Additionally, scalability is


significantly improved, making it easier to integrate new panel PCs into the network without requiring additional power sources. Another key benefit is reliability, as PoE


technology oſten includes power redundancy features that ensure uninterrupted operation, even during power fluctuations. By leveraging PoE-powered panel PCs, semiconductor manufacturers can achieve a more efficient, flexible, and cost-effective computing infrastructure across their production environments. Te space-saving potential of panel PCs


can be amplified by pairing PoE technology with smart mounting solutions designed specifically for compact environments. Wall- mounted, swing-arm, or flush-mounted panel PCs minimise intrusion into valuable work areas, freeing up floor and counter space for essential equipment and processes. Tese combined approaches allow


manufacturers to install and operate essential computing equipment in even the most space-constrained locations, without compromising functionality or accessibility. By reducing cable, eliminating separate


power sources, and offering flexible mounting options, PoE-enabled panel PCs become an ideal choice for semiconductor manufacturers looking to maximise both their available space and operational efficiency. Manufacturers are increasingly adopting


Power over Ethernet to enhance flexibility in panel PC deployment. Tis allows panel PCs to be seamlessly integrated with Human- Machine Interfaces (HMIs) in various mounting configurations, maximising space efficiency and adaptability across production environments. As an example, when operator workstations


are required within tight confines, highly flexible stainless steel pendant arm designs can save a significant amount of space, according to Shu. With the screen and connected keyboard suspended by a pendant arm mounted to a wall, the user can extend, rotate, and swivel the workstation into the ideal position. Aſter data entry is completed, the workstation can be pushed back against the wall, out of the way. When installing workstations in hallways or


other space-constrained areas, wall-recessed units are the perfect solution. According to Shu, 15-, 17-, 19-, and 21.5-inch touchscreen displays can be fully recessed into a wall to allow greater clearance. Tere is also an option for a 55-inch large-format 4K display workstation with Quad View display so operators can visualise KPIs and take full control of the production data. With flexible mounting options, scalability


is further enhanced since plants can easily add new PoE panel PCs to the network without the need for additional power outlets, facilitating system expansion as required. For semiconductor manufacturers,


combining compact panel PCs, PoE (Power over Ethernet), and versatile mounting offers far more than space savings. With smaller footprints, fewer cables, and flexible placement, manufacturers free up valuable floor space while gaining agility to reconfigure lines as needs evolve.
